GRAIN-BINDER,

SPECIFICATION forming part of Ressued Letters Pat-ent No. 1 1,103, dated August 19, 1890.

Original No. 336,895, dated March 2, 1886. Application for reissue iled March 25, 1887. Serial No. 232,424.

To all whom, it may concern/ Be it known that I, PETER PAUL CoLER, a citizen of the United States of America, residing at Clyman,in the county of Dodge and Slate of Visconsin, have invented certain ynew and useful Improvements in Automatic Grain-Binders, of which the following is a specification.

My invent-ion relates, so far as this present division of my reissue is concerned, to special improvements in the tripping, tying, and holding mechanisms of a binder, and in the general organization of the machine, all substantially as hereinafter fully set forth and pointed out in the claims. p

of a binding attachment for a harvester, formed, as usual nowadays, in a single casting, with tubular overhanging arm A', in which the tyer-shaft takes bearing, and corresponding subtending arm AX, which incloses the needle-shaft. Bolted to ears or projections a d' from this subtending arm are transverse l'netalframe bars or girts A2 and A3, the former at the rear of the arm and the latter adjacent toits front end, and to the inner or grain ends of these girts is firmly secured a longitudinal rod or frame bar A4, corresponding in length tothe length of the binder attachment and serving'as the means of connection between binder and harvester frame. Eyebolts b, embracing this longitudinal rod, secure pivotally thereto the inner ends of timbers B, carryin g the binder-deck or graintable B', the under side of which latter toward the delivery edge is provided with a toothed rack Z7', that is engaged by a pawl b2, sleeved upon an outer longitudinal frame bar or rod B2, supported from the harvesterand secured to the subtending arm of the post- Arepresonts the post-frame or main bracket IOO frame, so that by adjusting this pawl along the rack and securing it against accidental displacement by means of the set-screwihs, passing through its hub and binding against "the supporting rod or pivot, the inclination of the binding-table may be altered, as deemed expedient. A wind-boardend plate, or guard C is bolted to a web from the post of the main bracket and extends thence inwardly along and above the rear metal frame-bar and at its eXtreme inner lower end or corner is steadied andbraced by a strap or angle-iron c, secured to said bar.

D is the needle-shaft journaled, as already stated, in the subtending arm of the main bracket and carrying at its front end beyond Y said arm and secured in any suitable manner the needle or binder arm D', which has the customary concentric guard D2, to cut off in coming grain and makea clean separation as the needle rises, and is provided, as usual,with

a groove along its back for the reception ofthe cord, and with an eye near its point, through which said cord runs. To that end of the needle-shaft which projects beyond the subtending arm of the post-frame is loosely sleeved the outside tripping and compressing finger D3, having a bifurcated hub cl and downwardly-projecting arms or heel-extensions d therefrom, that lie on either side of and embrace the hub of the needle, which latter, being keyed to the shaft, serves to hold the trip-finger-in a fixed position and prevent its having any lateral movement on the shaft. Between the ends of these arms or heel-extensions is pivoted upon a pin d2, uniting them, one end of the link D4, the other end being slotted and connected' to a crank-arm D5, hereinafter referred to. y

Between the needle-shaft and the hub of .the trip-fin ger are interposed collars cl3, which are flush with lthe hub of the needle. Said collars are keyed to the shaft and form bearings for the trip-finger, which is free to oscillate thereon. One of the downwardly-projecting arms or heel-extensions of said trip-fin ger is provided with a lateral stud d4, which projects into a slot d5 in a hanger d from the subtending arm of the main bracket, thereby positivelylimiting the movement of the finger aboutits supporting-shaft.

The table-trip E is made of a single strip of metal folded upon itself, forming parallel arms, which are united at their outer ends and near their inner ends-,are provided with bearings e, which embrace the inner longitudinal frame-bar. At each side of the bearings a collar e is arranged upon the framerod,one being fixed and the other adjustable by set-screw e2, such arrangement permitting the ready removal of the table-trip from the rod,and also affording a means for taking up wear. Beyond the bearings the arms are bent or curved downward to bring their leverage below the fulcrum, and are united by a bolt e3 to one end of a link E', the other end of which is longitudinally slotted, as at e4, and

takes over the pin d2, that connects the heelextensions of the outside trip-fin ger, thus permitting to both the table-trip and the tripfinger a movement in one direct-ion. without necessarily affecting the position of the other, f butinsuring that the depression of the outer end ot' the table-trip shall rock the outside trip-finger in the same direction in which it would be rocked by t-he pressure of the grain -against it to cause its effective action. The

arms of the table-trip are disposed one upon each side of the binder-arm, the extreme outer end of said table-trip moving just inside of the trip-finger and in a plane'that when prolonged passes through said finger. In its normal position its outer end is raised somewhat above the level of the decking with the intermediate link pressing or pulling against the heel of the trip-finger, so that as the grain acmulates and is packed against the two it may either rock the trip-finger outward by direct pushing thereon or else press the table-trip downward, and thereby draw upon the link and impart to the trip-finger the same outward movement, or`else by concurrently pushing upon one and pressing upon the other actuate the tripping mechanism through both at once.

Upon the shank of the binder-arm are laterally-projecting studs carrying anti-friction rollers e5, arranged beneath thearms of the.

IOO

ment of the binding-arm and lift it against the gavel to compress the latter from beneath against the overlying breast-plate.

A F are the kickers7 or bu ndle-ej ectors, each of which consists of a`curved arm with one end firmly secured to a shaft F', while at its outer end it is provided with a backwardlyprojecting curved guard F2, movement of the same through the decking being provided for by slots made therein. The action of the ejectors will be explained farther on. The crank-arm D5, above referred to, is sleeved upon the ejector-shaft, which is hung in bearings Ff, formed in projections or ears on the subtending arm of the main bracket. This crank-arm has keyed to it at a point midway between its ends one end of a rod F4, while the opposite end of said rod is secured to one arm g of a bell-crank lever G, having its'fulcrum coincident with the ejector shaft. The other arm gf of the bell-crank lever is connected by a crank-pin g2 with al slotted bent connecting-rod G', hereinafter called the trip-rod, said pin passing through and sliding in the slot of the rod, while the upper or opposite end of said rod is connected with a trip-latch G2, which is sleeved upon a hub on .the upper tubular arm of the main bracket that, as already stated, incloses the tyershaft. also provided with a headed pin or projection l to start the binding devices.

g3, which passes through the eye of and is" thus connected to a short pintle g4, playingy loosely through a crank-arm g5 on the end of the ejector-shaft and encircled by a spring g; confined upon said pintle by a nut and bear-' ing against said nut and crank-arm, the pur-'5 pose of which connection is to permit the; outside trip-finger to'yield to the pressure off` the grain in resisting and forming the bung dle without imparting any movement to thei ej ector-shaft, said`connection serving also as;7 a means to return the trip-'finger to its norf mal position after the operation of the ej ect-i ors and during the time when the latter are? returning to their iirst position.

The nose of the trip-latch is hooked, in ,or-l der to catch .the trip-dog, and through its heel end, to which the trip-rod is connected as just explained, passes the upper bent end of a rod l'I, that restores the latch to itsnor-j mal position, and therefore maybe termed'A the resetting-rod, said bent end being se cured by nuts h h and serving as the pivot between the latch and trip-rod. The lower end of the resetting-rod plays through a swiv,l eled eyebolt h2 from an arm h3,v rigid`with.` the needle-shaft, and between this bolt and a, nut h4 on the rod is seated a coiled spring h5; whereby the rod is permitted to yield before; the latch when the latter is positively movedjy When these arei once started, the arm h3, with its eyebolt, is carried down .by the rocking of the needleshaft as the binderarm moves to encircle the" gavel, and the rod is thereby held in its depressed position, consequently holding thefl trip-latch with its terminal hook out of the pat-h of the trip-dog until the band is tiedl and the binder-arm again recedes.

A crank-arm h6 on the end of the needle-1 shaft is connected by a pitm an I-I with a wrist-- pin upon the main gear H2, keyed upon the'y tyer-shaft. This gear-wheel meshes into ai small pinion I, hereinafter styled the drivin g4; pinion, journaled on the cylindrical inner end of a clutch-sleeve l', which latter bears uponv its outer squared end t' the sliding hub t" of a chain or sprocket wheel l2, receiving motion from t-he harvester to operate the entire binder. This sleeve loosely embraces a shaft 13, supported in bearings i2 i3, formed in lugs projecting from the inner side of the overhanging arm of the main bracket and serving as the packer-shaft. The inner abutting? end of the sleeve is formed with aolutch-facej and it is moved automatically into engagement with an opposing clutch-sleeve I4, pinned to the packer-shaft by means of a coiled spring i4, disposed between its outer end anda nut at the extreme rear end of said shaft.;

The sliding sleeve, which, as just inti' mated, is driven by the chain-wheel, also car: ries two studs or projections k, which at dif-i ferent times are engaged by an anti-frictioni roller t" on the trip-dog K, which is pivoted upon a lateral pin k2 from a radial arm 7c3 of` `the driving-pinion, and the heel of which is the mechanism which they control.

arranged to be' caught by the terminal hook of the trip-latch, said roller being urged into engagement with one of the studs whenever the dog is released from the latch by means of a spring 7a4, fastened at one end to an arm 765, secured to the pivot-pin of said dog. During the engagement of either of said studs with the roller on the trip-dog, which follows the actuation of the tripping devices, the driving-pinion I partakes of the rotation of the constantly-driven sleeve l', .upon which it is mounted, and of course imparts motion to the main-gear and ty-er and needle shafts and One revolution of the main gear suffices to eifect the functions of all the binding devices, and in the latter half of this revolution as the binderarm recedes the hooked end of the trip-latcl1 is gradually carried down into the path of the trip-dog by the action of the resettingrod extending between its other end and the eyebolt that rocks with the needle-shaft, and just at the completion of said revolution and the attendent binding operations the hobkV will catch and stop the heel of the trip-dog, thus swinging it on its pivot and throwing its roller out of engagement with and out of the path of the studs on the sliding sleeve, thus disconnecting the driving-pinion from said sleeve and bringing it' to rest until the tripping devices are again actuated. Y

`YVhile the needle and tying devices are operating the sliding sleeve is held out of engagement with the clutch-sleeve upon the packer-shaft, so that the latter and the packing-fingers operated by it may remain idle; but at the moment that the separation takes place between the drivingpinion and the sliding sleeve the sleeve is left free to be car- IOO riedinto immediate engagement with theV clutch by the force of its spring, thereby again starting the packer-shaft to gather another gavel intothe binding-throat. This is accomplished by means of a forked shipper L, pivoted at Z to a lug Z from the head of the main bracket, the actuating-arm of said shipper having a rollerlg, which travels upon'an annular cam-flange Z3 on the inner face of the main gear, while its other forked arm embraces the fixed clutch-sleeve on the packershaft and is carried by the act-ion of said cam-flange against the inner face of the driving-pinion at the very outset of the revolution of the main gear, and through pressure upon said -pinion forces the slidingsleeve away from the fixed sleeve and holds it ont of engagement therewith until the conclusion of the binding operation, when the'cam-flange falls away, releasing the pressure upon the driving-pinion and sliding sleeve and allowing the latter to move into relengagement IIO with the clutch-sleeve at the moment the The teeth of said I segment gear at the propertiniewith a small pinion M', fast Ito a short shaft m', taking bearing in an offset m2 from the outer lower side of the overhung arm of the main bracket.

-The disk has at each end of its toothed segupon the escape of the pinion from said seglduring the further revolution of the main gear, holding the pinion motionless. A dog or hook 'm5, pivotcd to a projection onthe -main bracket, tits or rests upon a squared 'surface of the shaft m', to more effectively enable the horns to hold thev pinion against movement when at rest.

To the crank-arm m6 on the shaft fm. is pivoted by a pin and a screw-threaded sleeve m7, together with a jam-nut, one. end of a .link M2, which connects by a curved crankarm m8 with the ejector-shaft, whereby said shaft will be so actuated as to cause the ej ectors to move up and outward through the slotted decking or grain-table, so as to kick .or throw the bundle otf the platform after having been formed and bound and to recede beneath the table after such operation, the pinion M', the primary moving-power of said ejectors, being so adjusted or timed with relation to the toothed segment of the actuating-disk as to cause theejectors to move toward and to act upon the sheaf when the binder-arm moves away therefrom. Until the moment when the ejectors start toward the sheaf and the binder-arm begins to move away therefrom the outside tripping and compressing iinger has been held up against said sheaf opposing the binder-arm by means of binder-arm begins to recede the tripping and compressing linger moves outward before the ejector, or,in other words, is rocked outwardly upon its pivot by the action of the crank-arm S0' -cape unobstructed, and as the ejectors are retracted the compressor is returned concuron the ejector-shaft, so as to fall beneath the plane of the table and allow the sheaf to esrently to its normal position.

N N are the packing-lingers or packers, which are'pointed slightly-curved bars hung about centrally of their lengths upon oppositely-projecting cranks on the packer-shaft, whereby they are given an alternate action in accumulating and packing the grain into the binding-throat as it is received from the harvester preparatory to binding the sheaf. The upper ends or shanks of the packers are longitudinally slotted, as at n, and receive guide-pins n from the arms of a T-bracket N2, the base of which forms'the cap of the box that supports the inner end of the pack- @band in the tying operation.

err-shaft, the effect being that thecranks in their revolution impart an orbita-l movement to the point of each respective packer.

The tyer-frame O is bolted to offsets 0 o from the forward end of the overhung arm of the post-frame, the inner offseto being the same which at that end affords the pillowblock for the bearing of the packer-shaft.

The base of the T-bracket, besides serving as I of said frame, and thence extending to the outer legs, where it is again secured. Upon the upper side of the inner end of this breastplate is bolted a cross-bar O2, having forwardly-projecting pendent fieXible arms or stiff wires 03, against which the grain primarily accumulates and from which the packerscarry it onward wisp by wisp. The bindingtable is provided at its inner side and in precedence of these wires with inclined notched ledges o4-one on each side of the slot-t-hrough which thebinder-arm passes, to resist thev pushing back of the grain as the packers alternately withdraw from operation. In or about the middle of the breast-plate and opposite the slot in the binding-table is formed the cord-slot, above therear edge of which is disposed and secured to said plate a iiat spring o5, which, as the binder-arm passes through said slot, cleans the eye portion of said arm and the end of the cord which it carries of any foreign substances or grain that may have adhered thereto.

The knotter consists of a spindle P, provided at its lower end with a slightly-upwardcurved radial jaw p, the upper end of said spindle passing through the top plate of the tyer-franie and bearing in a support or casting thereon. Said spindle lis hollow, and through it passes a stem or rod P', having at its foot a lateral arm p', which serves, in conjunction withv the jaw upon the spindle, as a lower jaw to grasp the crossed ends of the Two otherl arms p2 from this stem curve upwardand act as guards to prevent the cord wrapping around the spindle while the knot is being formed. To open the lower jaw away from the upper, in order to receive the cord-strands between the two, vthe tyer-shaft, which extends directly over and slightly abovethe kno'tter, has a cam P2, arranged to act upon an adjustable head or shoulder p3 at the upper end of the stem, and an expanding spring p4,

l coiled about said stern and seated at one end against the head and at the other against the spindle, effects the closing of the jaws the instant the cam passes off. The tyer-shaft also carries a gear and cam wheel P3, that may be termed the tyer-cam, having a gearsegment p5 and the usual delay-ledge, the teeth of which segment mesh with and drive IIO a bevel-pinion p6 'upon the knetter-spindle once in each revolution of the tyer-shaft, thereby rotating the knotter to loop the cord and lay the knot. '.lhe heel of the upper knotting-jaw projects slightly beyond the spindle and is vertically slotted, as at p7, to receive a steady pin or dowel ps from the heel of the lower, whereby said lower jaw will be held in alignment with and partake of the rotation of the upper imparted by the spindle, but will be permitted to open away therefrom or close theretoward as induced by the action of the cam or spring upon its stem for the purpose of grasping the knot ends.

Q is the stripping-linger or loop-stripper connected to a shaft Q', extending through a sleeve or box q, fastened to the top plate of and depending therefrom within the tyerframe contigliously to the knetter-spindle. At or about the upper end of this shaft is a spring q', and above the latter said shaft is 'provided with a tappet-wheel Q2, against which the spring expands, thereby permitting the stripper to accommodate itself tothe rising and falling movement of the lower jaw of the knetter and holding it in contact with said jaw during the operation of forming the knot. The teeth of the tappet-wheel are engaged by asolitary tooth q2 on the tyer-cam just after the knotter has been rotated by the gear-segment on said cam, thereby vibrating the stripping-finger and causing it to push the loop off of the knotting-jaws, and immediately following the action of said tooth q2 an arm Q3, carriedby the tyer-shaft on the opposite side of the tappet-wheel from the tyercam, will strike and reverse said wheel to return the stripping-finger to its position of rest in readiness for the removal ot' the loop next formed.

In order to prevent the interference ofthe tyer-cam with the stripper-pinion after the latter has escaped from the first or actuatingtappet and to allow it to be reversed by the second or replacing tappet, the body of the tyer-cam is cut away, as at (14,11pon one side of the tappet @While upon the other side thereof the body is again cut away to produce an aperture Q5, into which a tooth of said pinion enters just previous to the engagement of its next tooth with said tappet to impart the requisite stroke to the stripping-linger and insure certainty of action of said parts.

The cord-holder is composed of two jaws, the first of which R is the positive jaw, and

`is formed as a hooked lever pivoted nearits upper portion to a swinging holder-frame R and having beyond the pivot a heel projection, which carries an anti-friction roller 7', normally traveling upon an annular flange or rim r on the tyer-cam, to hold said jaw positively against ,the other, but at the proper moment temporarily deilected by means of a cam-arm r2 from the tyer-shaft into a recess r3 in said rim, the effect of which is to open or retract the jaw. The positive jaw is slotted at its lower end to receive the end of av co-operating serrated jaw Rpivoted at its upper end to the same frame and held in contact with the rst by a spring r4 and prevented by means of a stopV T5 when its mate is withdrawn from following beyond a limited distance. A knife or cutter R3 is adjustably secured to the holder-frame, as shown'in Fig. 23, at the right-hand side of the needleopening therein and near the bottom edge of said frame directly in rearof the clampingedges of the two holder-jaws. V

The1 holder-'frame is hinged to or connected with the upper and outer corners of the knotter-frame by means of pivot-pins s s', the latter of which, being rigid with said holderframe, has an arm S, extending down outside of the knotter-frame and bearing against a spring s2, which itself` is seated upon a vstud s3, projecting from the side of said last-named frame, and acts to carry the holder outward against the stress of the binding-cord. From the upper end of one side bar of the holderframe extends inwardly a fixed arm S', that engages with a wiperS2 on the tyer-shaft, the purpose'of which is to cause'the inward movement of the frame,in order to allow the-cord held by the holder connected to said plate, as above stated, to readily yield slack to the looping action of the knotter. As soon as the cam passes off of said arm, the j ust-mentioned spring returns the frame to its normal or original posit-ion. A second fixed arm Ss extends inwardly from the holder-frame below the tyer-shaft and from the opposite side of said frame, and is acted upon by a wiper S4 upon said tyer-shaft, so as to hold the plate firmly or immovably when at the maximum limit of its outwardmovement.

In operation, when the binder-arm puts the cord around the bundle of grain the knetter makes a revolution, looping the cord around and receiving the ends between the jaws, which retain the cord by the action ofthe parts before described. At this juncture the cam-actuated holder -jaw releases the cord previously left by the binder-arm andgrasps the end of the new cord and forces it in contact with the knife, thus severing it. The stripper now acts, and a knot is formed in the cord. The ej ectors arrive immediately thereafter at their maximum limit of movement, discharging the bundle of grain from -the platform.
